絶縁油の劣化。In general, insulating oil filled in induction electric devices such as reactors in transformers or tanks expands and contracts with changes in the outside temperature and the temperature of the induction electric device itself, and has a so-called breathing effect. Seven devices absorb oxygen, moisture, and dust from the outside air, which comes into contact with the insulating oil and causes deterioration of the insulating oil over many years.

た空気の出入で吸収するものである。As a countermeasure to such problems, a diaphragm type conservator system has been used conventionally. Figure 1 shows a conventional diaphragm type conservator used with a companion transformer, a transformer tank 2 containing the transformer body lt is filled with insulating oil 3, a low pressure bushing V, a high pressure bushing J? In the transformer equipped with the transformer tank, a respirator 71 is provided in the diaphragm 61 and communicates with the atmosphere.
The main body of the diaphragm type conservator G2 is installed in communication with the main body G2. With this configuration, the action of the diaphragm 6 in the diaphragm conservator main body S causes expansion and contraction of the insulating oil J in the transformer conservator based on temperature changes. @ is absorbed by the inflow and outflow of air through the respiratory system z'2.

あるなどの問題がおった。However, in the conventional monolithic model conservator as described above, the pressure is atmospheric as it communicates with the main body of the M model conservator xpqFi respiratory system, so it has to be installed above the highest oil level of the transformer. In addition to the requirements for insulation dimension design of high-voltage wires, high-voltage bushings, etc., the height of the entire transformer increases, which has the disadvantage of making work at heights dangerous. Further, when transporting such induction electric appliances, it is customary to remove the conservator and other attached devices, which poses problems such as extremely troublesome transportation.

する。The present invention will be explained below with reference to the drawings. Figure λ 1 d is an embodiment of the present invention, which has an expandable hollow space for absorbing the expansion and contraction due to temperature changes of the insulating oil J filled in the transformer tank. The airtight container t is supported by a support tovr.
Therefore, it is suspended in the transformer tank and placed in the insulating oil 3. Hollow airtight container! A communication pipe/l is connected to the lower end of the
Interpose the valve and connect it to the pressure regulator IJK. This pressure regulator 13 maintains the internal pressure of the hollow airtight container 9 at a constant level and prevents the inside of the transformer tank from becoming negative pressure.

Since it can be arranged appropriately, the height of the entire transformer can be significantly lowered compared to conventional ones, and
Since the entire transformer is downsized, there is no need to remove sailing devices such as the pressure regulator/3 when transporting the transformer. In this example, the opening g2 is disposed in the companion iron core fastening member L so that the insulating oil 3 filled in the hollow airtight container 91- and the pressure vessel tank 91 can enter and exit. lsF′i coil.
